Thisinvention relates to latches, and especially a latch bf the tybe adapted for "use with kit hen cabinets or the like, an object being to provide a spring latch ofthis r 5 character which is of extremely simple construction, and which will be efficient and reliable in operatin. A'It' is particularly proposed to providea latch constructed from two main partsin the form of sheet metal stampings, and including an actiiating spring, and which parts 7 may be assembled with, facility by 'a; single operation. t y A furtherobjeetis tcprovrde 2m 1mmetel, and formed, to p'rpclu ce astructure of edges..
